Acme Dog Whistles

Acme Dog Whistles - We sell a full selection of Acme Dog Whistles to meet the varying requirements of trainers. If you are looking for a multi-purpose whistle the Acme Thunderer is similar to referee style whistle. Some have peas and some do not. A pea or a ball vibrates against a drum-like cavity to produce sound. In general, smaller the unit the higher pitch and pealess models tend to produce a higher pitch than whistles with a pea or ball.
